service equipment
service equipment. The necessary equipment, usually consisting of circuit breakers and
their accessories, that is located near the entrance point of supply conductors. This
equipment constitutes the main control and cutoff means of the supply.
service processor (SP). A physical component of the processor multifunction (PMF)
customer-replaceable unit (CRU) or I/O multifunction (IOMF) CRU that controls
environmental and maintenance functions (including system load functions) in the
enclosure. SPs operate in pairs to provide fault tolerance. The two SPs in group 01 of
an HP NonStop™ S-series server are designated the master service processors
(MSPs). Other pairs of SPs within a system are called expansion service processors
(ESPs). See also expansion service processor (ESP) and master service processor
(MSP).
service provider. (1) A person trained and qualified to service field-replaceable units
(FRUs). (2) An organization, such as the Global Customer Support Center (GCSC),
that helps you resolve problems with your HP NonStop™ server. OSM and TSM allow
you to use the help of a service provider by configuring client software to support
remote notification and remote access.
service side. The rear side of a HP NonStop™ S-series system enclosure. It contains
processor multifunction (PMF) customer-replaceable units (CRUs) or I/O multifunction
(IOMF) CRUs, ServerNet expansion boards (SEBs) or modular SEBs (MSEBs), and
ServerNet adapters. The service side is opposite the appearance side. All cables are
accessed from the service side. Most service actions are performed from the service
side. Service side doors are supplied with later NonStop S-series servers but are
optional on earlier servers. Service-side doors are cosmetic and are not required for
system cooling.
session. In the Open System Services (OSS) environment, a set of process groups
associated for job control purposes. A session can have a controlling terminal.
session leader. In the Open System Services (OSS) environment, the process that created
a session.
session lifetime. In the Open System Services (OSS) environment, the period that begins
when a session is created and ends when the lifetime of the last remaining process
group of the session ends.
setup configuration. A simple stand-alone network used to configure the OSM or TSM
environment. The setup configuration for an HP NonStop™ S-series server consists of
the server, the primary system console, an Ethernet hub, and two local area network
(LAN) cables. One cable connects the primary system console to the hub, and another
cable connects the hub to a processor multifunction (PMF) customer-replaceable unit
(CRU) in group 01 of the server. When OSM or TSM configuration is complete, the
setup configuration can serve as the working network configuration. Variations of the
setup configuration can be constructed using additional cables and hubs to increase
fault tolerance.
